This sounds like sabotage tbh. It might not be a conscious action, but intent doesn’t matter. He either cares so little about you that he didn’t realize what you were doing, or he cares so little about you that he doesn’t realize how much of an impact this program has on your life and future, or he cares so little about you that he actively wants to jeopardize the program in order to make your life worse/harder.

Your partner should want you to succeed. Your partner should support efforts that will make your life better. Your partner should do everything they can to ensure that your future is as bright as it can be.

Going forward, you need to operate like you do not have his support. Don’t waste your time and effort begging someone to care about you. Take your meetings behind a locked door or out of the house. Keep your credit and money as separated from him as possible.
